The Octet in F major, D. 803 was composed by Franz Schubert in March 1824. It was commissioned by the renowned clarinetist Ferdinand Troyer and came from the same period as two of Schubert's other major chamber works, the 'Rosamunde' and 'Death and the Maiden' string quartets.
Consisting of six movements, the Octet takes almost an hour to perform.
- Adagio – Allegro – Più allegro
- Allegro vivace – Trio – Allegro vivace
- Andante – variations. Un poco più mosso – Più lento
- Menuetto. Allegretto – Trio – Menuetto – Coda
- Andante molto – Allegro – Andante molto – Allegro molto
The Octet boasts the largest scale for any chamber work by Schubert. It is scored for a clarinet, a bassoon, a horn, two violins, a viola, a cello, and a double bass. This instrumentation is similar to that of the Beethoven Septet, differing only by the addition of a second violin.
In response to a reported request by Troyer for a work similar to Beethoven's Septet, Op. 20, Schubert composed the Octet in early 1824. The work was first performed at the home of Troyer's employer, the Archduke Rudolf (to whom Beethoven's Archduke Trio is dedicated) and included many of the musicians who premiered the Septet.
The basic structure of the movements is similar to those of the Septet, as are many of the key relationships between the movements and principal key (E-flat for the Septet, F major of the Octet). The theme of the first movement is derived from Schubert's song "Der Wanderer". The fourth movement variations are based on a theme from Schubert's Singspiel Die Freunde von Salamanka.
The Pascal Quartet with Jacques Dumont, violin I, Maurice Crut, violin II, Léon Pascal, viola and Robert Salles, cello, recorded the Octet in the early 1950's for the label (Musical Masterpiece Society MMS-2219).
The Melos Ensemble was founded to perform works such as the Octet for wind instruments and strings. The Octet was recorded in 1967 with Gervase de Peyer (clarinet), William Waterhouse (bassoon), Neill Sanders (horn), Emanuel Hurwitz and Ivor McMahon (violin), Cecil Aronowitz (viola), Terence Weil (cello) and Adrian Beers (double bass).
The Camerata Freden recorded it in 2003 with Adrian Adlam (violin I), Cristiano Gualco (violin II), Michael Hesselink (clarinet), Marjolein Dispa (viola), Michel Dispa (cello), Ilka Emmert (double-bass), Letizia Viola (bassoon) and Ron Schaaper (horn).
Janine Jansen (violin I) along with Gregory Ahss (violin II), Nimrod Guez (viola), Nicolas Altstaedt (cello), Rick Stotijn (double bass), Andreas Ottensamer (clarinet), Fredrik Ekdahl (bassoon) and Radek Baborák (horn) performed, and (video) recorded, the piece at the International Chamber Music Festival 2015 in Utrecht.
